UPDATE

Users in a similar thread posted that the teams are aware of this issue:

PSReadLine 2.2.0-beta1 and 2.2.0-beta2 do not work with this preview of PowerShell due to breaking changes in the prediction interface. The upcoming PSReadLine 2.2.0-beta3 release will resolve this. Use PSReadLine 2.1.0 as the temporary workaround.

---

Happening with me as well. Seems to be exclusive to PowerShell 7.2.0-preview.6.
Reproed several times with "-noprofile" in order to rule out profile issues; additionally, I commented out lines in my profile.ps1 that dealt with PSReadLine. Occurred initially when updating PSReadLine on a preexisting Powershell 7.2.0-preview.6 install; attempted to mitigate with fresh installations of both, but the issue persisted.
Tested on completely new sessions. I have not yet restarted the computer.

Steps to reproduce

Install PSReadLine 2.2.0-beta2
Install PowerShell 7.2.0-preview.6
Launch an instance of pwsh v7.2.0-preview.6 by any means:
• Directly running the executable by navigating to its installation directory
• Via Start Menu shortcut
• From powershell.exe as $PathToPS72\pwsh.exe -noprofile
• From command prompt as %PathToPS72\pwsh.exe -noprofile
• As terminal within VS Studio Code
• As terminal within Windows Terminal

Expected behavior

Typical PowerShell startup behavior--without errors and with a typical prompt.
Subsequent commands should exhibit the usual PSRealLine behaviors.

Actual behavior

Upon launching any instance of PS 7.2.0-preview.6, the user is presented with the given errors and messages. The console remains open and responsive, though there is no prompt available.

The user can type commands; text remains white. Pressing Enter will run the command and the expected output will be displayed, after which the included error messages appear. Prompt never appears.

Tab completion seems to be functional, though upon pressing TAB, another error message appears. The user's typed text moves to the center of the console, the suggested completion appears to the right of that, and another error message block appears above these, at the top of the console. The original error message and the caret remain at the bottom of the screen.

PSReadLine seems to be behaving fine with PowerShell 7.1.3.

Same issue for me after upgrading to preview 6. Initially, I had psreadline 2.2.0-beta1 installed, which throwed the same error as 2.2.0-beta2.

Thanks for reporting and using the preview version of PowerShell!
This is a duplicate of #2495. The powershell-7.2.0-preview.6 contains a release note for this:

PSReadLine 2.2.0-beta1 and 2.2.0-beta2 do not work with this preview of PowerShell due to breaking changes in the prediction interface. The upcoming PSReadLine 2.2.0-beta3 release will resolve this. Use PSReadLine 2.1.0 as the temporary workaround.

This was addressed by #2524. We will release 2.2.0-beta3 with this fix today or tomorrow.
